M invention is a stereo-t 3e slate casting i o iachine.

An ob ect of my invention is t no construe maciime in tion of a stereotype plate castin which the mold may be locked in a horizontal position and the cope opened by piv he floor for the pouring of the metal.

oti' to one Another object of my invention is theconstruction of a mold for a stereotype plate cas ng pivoted on a. liorizo'ital axis transly of the hold. the axis heir towards one end and such end has a count rwcight to balance the mold and the metal poured therein. This pivotal construction adjacent one end of the mold is adapted to position pouring gate when the mold is inclined at a convenient elevation above the floor for easy pouring. I

Another object of my invention is in the manner of pivoting the cope to one side 05 the drag or the mold and utilizing a. pair of legs connected to the opposite side of the cope from the pivotal mounting of the dra These legs have a lever construction to loosen the cope from the drag after casting and may be grasped as handles to swing the cope to the open position, the cope in this po- "t', supported on th legs.

Another object of my invention is in the manner of holdi' and pressing the cope 'o a proper it with the drag, this being done by a pair of reel; shafts on opposite sides of the drag, and having clamps frictionally mounted thereon.

The clamps are adapted to e: rim of the cope and by means 0 action between the l slits on the comp movement of such sh being rocked into engagementwith the cope downwardly thus forcibly the dra age over the an ccentric are given a pull locking the cope and Various other features of novelty will be apparent from the following description and the claims; and my invention is illus trated in the accompanying drawings, in which:

In constructing the casting machine I employ a suitable frame designated generally by the numeral 11, this having a pair of standards 12 on opposite sides, on which standards there is mounted a pair oi short pivot shafts 13 forming the pivotal connection of the mold designated generally by the numeral M to the frame. This connection is by providing the drag 15 with lugs 16 on the side through which the pivot sha ts 13 extend. (Note Figs. 1, 3 and 5.) The drag is trough shaped and has a rim 17 at one end and at the other end is provided with an inclined plate 18 adapted to form a rest in pouring the metal in the gate 11). At. each edge of the drag there is a removable rim bar Qt) confining the metal pouring between the side margins of the cope and the drag; and at the lower end a removable segment of a ring 20' to confine the metal between the cope and drag.

The drag at one end pins 21 from which depend curved links these links having a heavy counterweight 23 connected thereto, the counterweight fitting between the forward legs 24: of the frame, there being a guard plate 25 in front of the counterweight. The frame is provided with lugs 26 through which extend set screws 27, these set screws being adjustable to engage the bottom of the counterweight when in its lowermost position and carry their weight. This counterweight swings from the position shown in Figs. 1. and l to that shown in Fig. 2 in the operation of the machine. A matrix 27' fitted in the drag.

The cope designated generally by the numeral 28 is formed with a transverse curvature concentric with that of the drag and at the upper end has a sloping section 29 which functions with the upper end of the drag to form the gate .19. At the lower end of the cope there is a transverse section 30 which fits against the end rim 17 preventing the escape of the metal in pouring. Hinge leaves 31 are attached to one side of the cope. there being two such leaves illustrated, and these are pivoted to the fixed arm 32 of the hinge connected to the drag by hinge pintles 33. A pair of legs 31 are titted in a block 35 shown in detail in l igs. 10 and 11, and these blocks are mounted on pivot pins 36 mounted in cars 37 secured to the upper part of the cope on the opposite side to that of the bin e leaves 31.

lormed integral with the blocks 35 there are short bow-shapcd pressure levers 38 which have a pressure exerting end 39 adapt ed to bear against the upper outside edge 40 of the drag. There is a set screw 41 which extends through the pressure lever and is adapted to have its lower end with a slight clearance above the edge 42 of the cope. This set screw may be adjusted by a clamping nut mounted thereon. There is also a set screw 43 which extends through the pressure level and bears on the pin 36 forcing this pin to rock with the block 35 in the journals in the cars 37.

On each of the blocks 35 there is an abutment boss ll which is adapted to have a slight clearance from the upper curved surface 45 of the cope when the pressure end 39 is in contact with the edge 40 of the drag.

The action of the legs and the pressure lever 38 is first to relieve the cope after provided with pivot pouring of the metal. The operator may stand at one side of the cope and by a quick thrust or a pull on the upper ends of the legs 3 he may rock the pressure levers so that the pressure end 2}!) forcibly engages the edge 40 ot the drag, thus slightly elevating the cope until it comes in contact with the ad ustable set screw 4.1. This action loosens the cope from the cast metal and allows it to he tilted up ardly on the hinge pins 33 until the ends of the legs rest on the tloor thus exposing the complete interior of the drag.

The clamping and locking mechanism for the cope and drag comprises a pair of rock shafts 46 mounted on opposite sides of the' drag. These are. illustrated as being journaled in a. pair of closed journals 47 adjacent the ends of the drag and open journals it? in the intermediate positions. As shown in detail in Figs. (3 through 9, and 12, the shaft has a reduced diameter 49 at the journals and an enlarged diameter 50 between the journals, and on this enlarged diameter hook-shaped clamps 51 are frictionally mounted.

This friction mounting utilizes an annular groove 32 in the enlarged portion 50 in which groove fits the tongue 5?. of a slidable pin at, this pin being mounted in a cylindrical extension 55 of the. clamps 51, there being a pressure spring 56 bearing against the pin 54 and the adjustable screw plug 57. This pressure is sutlicient so thatnormally when the rock shaftis partially rotated by the hand crank 58 the clamps are carried with the shaft.

llach ot the clamps is provided with an adjustable set screw 59 adjacent its outer end and on the inner face. there is a fixed boss (30. This fixed boss is adapted to engage the outer surface (51 of the drag adjacent its edge and the set screw to contact with a beveled surface (3'2 on the upper edge of the cope. (Note Fig. 7.) There is also a boss till on the end of the extension 55, this boss being adapted to come in contact with the lower surface of the drag below the rock shaft as indicated at (34. (Note Fig. 9.)

The action of the clamps is as follows. presuming the mold to be in a horizontal position and the cope to be closed over the drag as shown in Fig. 1: ()n the rocking movement of one of the rock shafts 46 through the medium of the crank 58 the clamps are shifted from the position shown in Fig. 1 to that shown in Figs. 2 and 3 until the set screws in each of the clamps contact with its abutment surface 2 and the bosses (it) engage the outside of the drag adjacent its edge. As the reduced portion of the shafts 5!) journaled in the journals r? and 18 is eccentric to the surface 50 on which the clamps have frictional rotation the further movement of the hand lever Cir rocking the shaft 46 gives a downward pull on the clamps 51 thereby pressing the cope into a tight fit with the marginal edges of the drag. On the releasing movement the first action of the rock shafts is to loosen the clamps by giving them a slightly upward movement relative to the ournals 4:7 and 48 until they are released from the cope and then the further movement carries the clamps through the medium of the frictional engagement with the rock shaft from the position of 7 to that of Figs. 9 and l, he bosses contacting with the under portion of the drag.

The latch device designated generally the numeral 65 has a handle 66 mounted a pivot stud 67 secured to a boss 68 which is ureferably formed integral with the stand by Oil ard portion 12 of the frame 11 and on on ride. The stud 67 has a latch finger 69 which is adapted to engage on either side of a nub 70 on a boss Tl formed on one of the lugs 16 extending outwardly from the (Note Figs. 1 and 5.) In Fig. 5 the position is illustrated in which the mold is in a horizontal position and tilting of the 'lOlCl downmmdly to the position of Fig. 2 is by the lat-7h linger 69 bearing rest the nub 70 and the boss 71, and any rating irovement thrusting the end of the the uh T0 and the boss 7i. thrust upwardly and . owards the front part of tchine from the top of the cope. l'. mold is tilted into the position of l L latch linger 69 engages on the of the nub 70. The adjustable screw 73 mounted in a cross rod 74lhetween the bottom rails '75 of the frame limit the tilting motion of the mold. The two sides of the frame are held in adjusted position by bolts 76 having sleeves T7 thereon. It will be noted that when the mold is tilted in the position of *ig. 2 that the pouring gate is at a. convenient elevation above the floor so that an operator may stand. in front of the machine and po -r the molten metal through the gate.

A feature of my invention is that the mold is pivotally mounted on the frame near the upper end when the mold is tilted and therefore the pouring gate is at a convenient height above the floor level so that the metal may be readily poured into the gate by a person standing on the floor.

The function of the counter-weight is to c tilting of the mold back to the h .ri-

when the metal has hee V n, tlat is, when the casting has made, it will he seen by the relation the pivot points of the mold to the frame that large proportion of the stereotype plate is n the side of the pivots opposite the counend of the drag,

ter-weight Therefore with this counter weight it is comparatively easy for a person to tilt the device from the inclined position into the horizontal. hfloreover, the counter weight helps to balance the part of the mold on one side of the mounting pivots.
